Given numbers are 558, 687, 679, 395

The list of prime factors of all numbers are

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 687 are 3 x 229

Prime factors of 679 are 7 x 97

Prime factors of 395 are 5 x 79

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 558, 687, 679, 395

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(558, 687) = 127782

GCD(558, 687) = ( 558 x 687 ) / 127782

= 558 / 687

= 558

Step2:

LCM(3, 679) = 2037

GCD(3, 679) = ( 3 x 679 ) / 2037

= 3 / 679

= 3

Step3:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

So, Greatest Common Divisor of 558, 687, 679, 395 is 1
